I have a quick question, which despite nearly 2 hours of searching and reading I can not find a solid answer for.

We are installing a upgraded Greddy Turbo kit which included blue upgraded (read: cap ground off) injectors which were flow tested. According to a post by Mazda Maniac, larger injectors should always be installed in the P2 position.

This is diagram shows the P2 injectors as the 2 center injectors on the secondary fuel rail. (FS PF2 PR2 RS)

Am I correct in my placement? This car will be being tuned this Saturday by Mazda Maniac.

(The only reason I ask is the seller of the injectors told the owner to be sure to install them on 1 and 4, not 2+3 due to the tuning issues he had when they were installed.)
Thanks!

Hey Marc, did not realize you started this thread I asked the same question in our local MM dyno thread (link below). MM replied saying they should be installed as you did. I appreciate you checking on this!

they should go in the p2 position (the center two)
